You won't do it all. Knowing how many days you are going would help break it down! On our first trip we did 2 days MK and 1 in each of the others. 1 was enough for us, personally, in ak and hs. I wish we had done 2 in epcot. 3 would be nice in mk. It also depends on how busy it is when you go. We went at a low crowd time and did a lot, but there is still more we want to do.
